export matrix to csv in matlab

To export a matrix to a CSV file in Matlab, you should use the csvwrite function. The first argument to this function is the filename to write to, and the second argument is the matrix to be written.

Here is an example:

main.m
M = [1 2 3; 4 5 6; 7 8 9];  % Example matrix
filename = 'output.csv';  % Name of output file
csvwrite(filename, M);
116 chars
4 lines

This will create a CSV file in the current working directory with the name output.csv, containing the contents of the matrix M.

Note that csvwrite writes numeric data only, so if you have a matrix with mixed data types, you need to convert it to a numeric matrix first.

If you want to include row and/or column headers in your CSV file, you may need to use a more specialized function like writetable or writecell.
